基于区块链动态合作博弈的多微网共治交易模式

随着前沿信息技术在智慧能源系统中的广泛应用,能源互联网下的多能源交易市场面临着诸多新的挑战。基于区块链技术构建微网群中聚合商与多个微网2类交易主体间的共治交易环境,设计区块链聚合商–微网群联盟交易架构及区块数据结构,针对包含冷热电联供系统的微网及聚合商2类区块链节点,以多能互补为基本原则建立考虑碳配额机制及环境标识因数的节点模型;基于聚合商及微网节点间的能源交易新模式,设计动态合作博弈的环境标识因数激励机制及多目标进化算法支撑的智能合约,并提出共治系数用以评估所提微网群运营策略的有效性;最后,经算例仿真验证表明,区块链共治交易模式在保证各交易节点效用的基础上,可为多能源协调优化互补提供有力支撑,促进可再生能源发电就地消纳,有助于微网群的低碳可持续发展。

Multi-Microgrid Co-governance Transaction Model Based on Dynamic Cooperation Game of Blockchain

With the wide application of advanced information technology in smart energy system,the multi energy trading market under the energy Internet is facing many new challenges.Based on the blockchain technology,this paper constructed a co-governance transaction environment between aggregators and multi-microgrid in the microgrid cluster,and designed an alliance of aggregators and microgrids cluster transaction architecture and its block data structure under the blockchain network.Based on the principle of multi energy complementary,a node model considering carbon quota mechanism and environmental identification factor was established for the aggregator nodes,and the microgrid nodes including combined cooling heating and power(CCHP)system.Based on the new energy trading mode between aggregators and microgrid nodes,the environment identification factor incentive mechanism of dynamic cooperative game and the intelligent contract supported by MOEA/D(multi-objective evolutionary algorithm based on decomposition)were designed,and the co-governance coefficient was proposed to evaluate the effectiveness of the microgrid group operation strategy.Finally,the simulation results show that,on the basis of ensuring the utility of each transaction node,the block chain co governance transaction mode can provide strong support for the coordinated optimization and complementarity of multiple energy sources,it also can promote the local consumption of renewable energy power generation,and contribute to the low-carbon sustainable development of microgrid cluster.
